+# .gitignore file for Xcode4 and Xcode5 Source projects
+#
+# Apple bugs, waiting for Apple to fix/respond:
+#
+#    15564624 - what does the xccheckout file in Xcode5 do? Where's the documentation?
+#
+# Version 2.6
+# For latest version, see: http://stackoverflow.com/questions/49478/git-ignore-file-for-xcode-projects
+#
+# 2015 updates:
+# - Fixed typo in "xccheckout" line - thanks to @lyck for pointing it out!
+# - Fixed the .idea optional ignore. Thanks to @hashier for pointing this out
+# - Finally added "xccheckout" to the ignore. Apple still refuses to answer support requests about this, but in practice it seems you should ignore it.
+# - minor tweaks from Jona and Coeur (slightly more precise xc* filtering/names)
+# 2014 updates:
+# - appended non-standard items DISABLED by default (uncomment if you use those tools)
+# - removed the edit that an SO.com moderator made without bothering to ask me
+# - researched CocoaPods .lock more carefully, thanks to Gokhan Celiker
+# 2013 updates:
+# - fixed the broken "save personal Schemes"
+# - added line-by-line explanations for EVERYTHING (some were missing)
+#
+# NB: if you are storing "built" products, this WILL NOT WORK,
+# and you should use a different .gitignore (or none at all)
+# This file is for SOURCE projects, where there are many extra
+# files that we want to exclude

+## How to add new topics or materials
+
+#### Steps
+
+![Content screenshot](CONTENTSCREENSHOT.png)
+
+1. Go to `RoadmapProject/Script`
+1. Open `Content.yml`, add topics or links to materials
+1. Run `main.swift`
+1. Commit and push all generated files and changes
+1. Submit a pull request
+
+Note. I've used Sublime text for editing YAML.
+
+#### Prerequisites
+
+1. Git
+1. Latest Swift/Xcode
+1. Fork of the repository
+1. Prepare PlantUML:
+	1. Install [JDK](http://www.oracle.com/technetwork/java/javase/downloads/jdk9-downloads-3848520.html)
+	1. Install Homebrew:
+		- `/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"`
+	1. Install GraphViz:
+		- `brew install libtool`
+		- `brew link libtool`
+		- `brew install graphviz`
+		- `brew link --overwrite graphviz`
+	1. Go to `Roadmap Project/Script/` 
+	1. Run `java -jar plantuml.jar -testdot` to check if installed correctly.
+
+#### How to debug script
+Use `Roadmap Project/Roadmap.xcodeproj` to run and debug script.
+
+Xcode runs and debugs an executable binary, thus generated output will be put next to the binary.
+
+Always run script via terminal before submitting a PR.

+# 🚀 iOS Developer Roadmap
+Roadmap to becoming an iOS developer in 2018
+
+## ☝️ What is it?
+This is a tree-like compilation of topics highly relevant to iOS development. Both image and text version are generated from human readable content file.
+
+## ✌️ Who is it for?
+The roadmap will be helpul for:
+
+- anyone who wants to become an iOS developer
+- iOS developers who desire to become experts
+- iOS developers who are preparing for interviews and need to brush up knowledge
+- iOS developers who need to compile own set of interview questions
+
+
+## 👌 Why these topics?
+See [this article](https://medium.com/@borlov/c9a24f413457) explainig selection of topics.
+
+## 👨‍🎓 How to use this roadmap
+1. Find a topic you want to study.
+2. Go to corresponding resources section.
+3. Study untill you can confidently explain the topic to your cat.
+4. (Optional) tick the checkbox next to the topic. [How to tick a checkbox](HowTo/HOWTOCHECKBOX.md).
+4. Go to step 1.
+
+`Essential topics` are topics which significantly contribute to understanding of iOS development. Consequently, it is a good idea to study them first as they are often encountered on interviews.
+
+Start from `Getting started` section if you haven't done any iOS development yet.
+
+## 🗺 Image version

+## 🤝 How to contribute
+
+- add additional topics 
+- add missing study materials 
+- throw ideas at me on Twitter [![Twitter URL](https://img.shields.io/twitter/url/https/twitter.com/kamranahmedse.svg?style=social&label=@bohdan_orlov)](https://twitter.com/bohdan_orlov)
